- Diagnosis
- Fronds pinnatifid with winged stalk; margin of pinnae
entire, base excurrent; apex of sterile pinnae acute or obtuse, base
more or less constricted; fertile pinnae with acute apex, base not
constricted. Veins prominulous; primary vein strong and straight;
secondary veins straight or sometimes zigzag; areoles irregular or
quadrangular, occasionally with one unbranched veinlet. Sori round,
apparently lacking indusia, close to the primary vein and arranged in
one row on each side of the primary vein; one sorus per areole along the primary vein, compital. In situ spores elliptical in polar view, beanshaped
in equatorial view, monolete, planoconvex, and exospores
verrucate.
